89 635 security remote unit
Got another one for the pro's on the net.
Got a 89 635 with a factory installed (alpine) security system in it that came with two fobs. One of those fobs was lost in a move and took nearly two years to find a replcement dirct from Germany.
For clarity I will refer to the control unit as control unit. the original fob as FOB 1, and the replacement fob as FOB2.
When FOB 2 arrived my mechanic married it to the control unit as prescribed in the Alpine security insatructions that came with the car. Upon testing we found that both FOB 1 and FOB 2 operated wiithout any problems.
But a couple of weeks later FOB 2 failed to operate any more while FOB 1 operated normally.
Last week FOB 1 stopped operating completely and after checking all fuses, and wiring it was determined that the FOB had failed and the rest oif the system was good.
The next day I was fooling around wit FOB 2 and upon pressing the lock buttom found that it was working again and we can't figure out why that should happen unless the unit is a rolling code system that requires going back and re-marrying bot FOB 1 and FOB 2 in the control unit again.
Finally, we had thought to just buy a replacement micro chip package of three or four micro chips but they are impossible to find.
Okay guys -- HOW DO WE FIX THIS??? --- PLEASE
